From a point exactly midway between the foot of two towers Pand Q, the angles of elevation of their tops are 30° and 60°, respectively. The ratio of the height of P to that of Q is ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 ie 1 : 3.
tan 60 = Q/√3 , tan 30 = P/√3
√3 = Q/√3 , 1/√3 = P/√3
Q = 3, P = 1
P : Q = 1 : 3
